The document discusses the various feelings a teacher experiences with different student groups. With intro-level students, the teacher feels surprised and wonderful when students accomplish tasks and speak for 5 minutes in English. However, with advanced students who are expected to speak only English, the teacher feels upset and annoyed when they speak Spanish, having forgotten they are in an English class. To regain control, the teacher allows students 5 minutes to speak in their native language, then begins the normal English-only class. The teacher experiences a range of emotions from feeling like a wonderful teacher with eager intro-level students to feeling unable to control talkative advanced students.
